Clinically, according to the volume, size and nature of the patient’s large intestinal polyps, different treatment methods can often be taken: a. If the patient performs colonoscopy, found small size of large intestinal polyps, and scattered multiple, polyp surface smooth, regular morphology, mostly considered benign lesions. At this time, patients can be advised to perform endoscopic polypectomy of large intestine and complete hemostasis of the trauma. Endoscopic polypectomy is less traumatic, and patients can move normally for twenty-four hours after surgery, which can also effectively prevent polyps from becoming cancerous, which is the most important clinical treatment for colorectal polyps. Second, if the size of the polyp is large or the surface of the polyp is accompanied by erosion, bleeding and cauliflower-like changes, it is highly suspected that the polyp is cancerous. In this case, laparoscopic resection of the diseased intestine and regional lymph node dissection if necessary are needed to completely remove the polyps and achieve a better treatment effect.
